Online Aggregation of Coherent Generators Based on Electrical Parameters of Synchronous Generators
This paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. An interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. Hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...
متن کاملcomparison of conventional salient-pole synchronous generators and permanent-magnet-assisted salient-pole synchronous generators based on finite element analysis
this paper presents a novel salient pole synchronous generator i.e. permanentmagnet-assisted salient-pole synchronous generator (pma-sgs). due to saturationof conventional synchronous generators (sgs), permanent-magnet-assisted salientpolesynchronous generators (pma-sgs) are presented. pma-sgs are a new type ofsalient-pole synchronous machines with extra permanent magnets (pms) betweenthe adjac...

متن کاملA Simple Analytic Method to Model and Detect Non-Uniform Air-Gaps in Synchronous Generators
The air-gap of electrical machines may become non-uniform due to low accuracy of the manufacturing machinery, in assembling processes, or by aging. Detection and monitoring of this phenomenon is very important and of interest. There are several methods to model non-uniform air-gaps and to detect them by monitoring systems. One of the most widely used methods is by the analysis of the line curre...
متن کاملIslanding detection of synchronous distributed generators
This paper analyses the performance of local passive islanding detection methods for synchronous distributed generators, under different grid and load scenarios. These methods monitor electrical parameters at the interconnection point of a distributed generator and detect island situation whenever these parameters change correspondingly. Lately, islanding detection research has been focused on ...
